Lette/rs Patent No. 99,882, dated February 15, 1870.

IMPROVED RAILWAY-CAR AXLE-BOX.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, J CHN-T. HAGERTY, of Camp Point, Adams county, and State of Illinois, have in- Vented new and useful Improvements in Car Axle- Boxes and Oiling the Journals; and I do hereby declare the followingVt-o be an exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification, in which- Figure l represents a side elevation, exhibiting the interior of the boxin dotted lines, with the lubrieator at rest.

Figure 2 shows an end view of the interior of the box, and exhibiting the lubricator raised and in posi tion foi-piling the `journal by the operation ofthe screw-propeller above.

The nature of my invention consists in the coustruction of a screw-propeller, located on a shaft or windlass, forming a spiral windlass, in the center of which is a chain attached, and conneetedwith an upright arm that supports a horizontal frame that carries with it a concave lubricator that israised and lowered to and from the lower side of the journal of theaxle, for the purpose of oiiing the journal, by the` revolution of t'he windlass that is propelled by the resistance of the atn'iosphere while the cars are in motion, the ,windlass being located at the upper side aud front end of the journal-box.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. l

A represents the spiral windlass, and B the lubricator. The windlass is intended to he made of castiron, with spiral anges on the out-side.

The center of the windlass is groos'ed, for a chain, C, to wind up around it, one end of the chain being connected to the center of the wndlass, and the other end to `the upright arm .1), that supports a forked frame, E, at the ends of which the concave lubricator B is suspended at its'centre (on each side) by pivots or hooks G.

'lhe spiral windlass A is located on -the upper side and 'upon the outer end of the journal-box H, itsjournals revolving in two upright posts, J J, and as the windlass is revolved by the air, the chain G is wound up, 'drawing with it the arm D, with its` lubrcator E, until it is sueiently nea-r to the lower side of the caraxle K, that it can be supplied with oil that the lubricator has carried up from the bottom of the box H, and the moment the cars stop the spiral windlass A ceases to revolve, and the lubricator drops again, by its own weight, to the bottom oi' the box.

The braces L L are supports for the journal K, operating on the inside of `the box H.

That I claim as my invention, and desire to secure by Letters Patent, isn The spiral windlass A, in combination with the lubrieator B, when construct-ed and operating as herein deseribech, and for the purposes set forth.

JOHN fl. HAGERTY.
